GPIO6	UART_CTS	none		27		H3-5, H5-7, H9-17
GPIO7	UART_RTS	none		28		H3-6, H5-1, H9-19
			wake	3		H3-2
	UART_RX			7		H3-3, H5-3, H9-15
	UART_TX, Boot control 1					8	H3-4, H5-5, H9-13
	RESET_N			26		H9-1
	CHIP_EN			34		H3-1
				35	Thermistor	H3-7, H9-7

1 : The Boot control pins must be at the following levels immediately after a reset in order for the module to boot correctly: UART_TX = GND, GPIO2 = VDD, GPIO3 = VDD

Headers

H2 - Expansion
H3 - Expansion
H5 - Peripheral
H6 - Debug
H9 - Isolation Jumpers - Note : Solder bridges on the bottom of the evaluation board short out the jumpers by default. Remove the bridges before using the H9 header.
